2 Claims.

The present invention relates to chair seats and more particularly t6 seats for chairs of the opera type.

The primary objects of the instant invention are to provide an upholstered seat for a chair of the opera type whose fabric covering is secured thereover and under the seat in a novel manner; to provide such a chair seat having a sheet metal bottom rim provided with a plurality of stamped spaced fingers adjacent its circuitous length adapted to be pressed into clamping engagement with the peripheral length of the upholstered fabric for securing the fabric covering over the seat in a taut position; and, to provide such a chair seatwhich is simple in construction, utilitarian in use and economical in manufacture.

Illustrative embodiments of the invention are shown in the accompanyin drawing, wherein- Figure 1 is a top plan view of the chair seat, a portion of its seat covering and padding being broken away;

Figure 2 is a side elevational view thereof, a portion of one comer of the seat covering being broken away;

Figure 3 is a bottom plan view of the chair seat, certain of the seat supporting springs being only partially shown;

Figure 4 is an enlarged sectional view of the chair seat on line 44 of Figure 1;

Figure 5 is an enlarged fragmentary view of a portion of the sheet metal seat bottom rim and fabric covering for the seat showing the manner in which the covering and a seat supporting spring are secured;

Figure 6 is a sectional view thereof on line 6'6 of Figure 5; and

Figure '7 is a sectional view of a modified construction, differin from the construction shown in Figure 6.

Referring then to the drawing and firstly to Figures 1 to 6 inclusive wherein like parts of the construction shown are designated by the same numerals in the several views, the chair seat comprises a sheet metal seat supporting rim l0, here shown as channel in form, whose circuitous length between its oppositely flanged portions l I, I2 is provided with a plurality of spaced downwardly struck-out portions forming fingers l3.

The rim I is further provided with a plurality of pairs of oppositely disposed apertures l4 along both of its opposite sides (Figure 6) and as shown, springs l of the sinuous type are secured at each of their opposite ends in spanning relation between opposite sides of the rim I0 by means of looped clips l6 whose opposite ends H are projected through the apertures ll of each pair and thence curled outwardly, all as best shown in Figure 6.

Padding l8 of hair or other suitable material is disposed over a sheet I! placed upon the parallelly disposed springs l5 and a covering material 20 is disposed over the top of the seat, its

opposite sides and ends being secured in taut or stretched position by the clamping engagement of the fingers l3 pressed from the position as indicated in dotted lines in Figure 4 to the position as indicated in full lines in the same view and against the marginal lengths and widths of the covering material 20 which is preferably folded back upon itself as shown in Figure 4.

In the modified construction shown in Figure .7, the channel sheet metal seat supporting rim I0 is provided with a plurality of spaced upwardly struck-out looped portions H6 between its oppositely flanged portions ll, l2 and along its opposite sides whereas the circuitous length of the outer flanged portion ii of the rim I0 is provided with a plurality of spaced inwardly struckout portions forming fingers l3.

Here again springs l5 of the same type are secured at each of their opposite ends in spanning relation between opposite sides ofthe rim III by means of the looped struck-out portions H6 through which loops the opposite ends of each spring is passed. Similarly the covering material 20 is secured over the top of the seat, its opposite sides and opposite ends in stretched or taut position by the clamping engagement of the several fingers i3 pressed into position against the marginal lengths and widths of the covering aterial folded back against itself.

It will thus be seen that the covering material v constructions shown may be altered or omitted without departing from the spirit of this invention as the same is defined by the following claims.

We claim: 1. A channel sheet metal supporting rim for a. chair seat whose opposite sides between its flanged portions are provided with a plurality oi spaced upwardly struck-out looped-portions,

each adapted to retain an end of a seat supDOrt-.

ing spring in spanning relation between the opposite sides of the rim and whose outer flanged portion is provided with a plurality oi spaced struck-out portions forming fingers adapted to- I stretched over the top, opposite sides and op- 5' I posite ends of a chair seat supported upon said 2. A chair seat having a sheet metal rim provided with a plurality of spaced upwardly looped portions and having a plurality of spaced struckout portions forming jfingers; a plurality of springs in spanning relation between the opposite ends of the rim whose opposite ends are each retained within one of said looped portions, and a covering material stretched over the springs and over opposite sides and opposite ends of the rim whose marginal edges are Irictionally retained between the struck-out fingers and the openings formed thereby by the pressed clamping engagement of the fingers against the marginal edges of said covering material.
